PHYTOCHEMICAL SCREENING AND ANTIMICROBIAL ACTIVITY OF BARK EXTRACT OF HARPULLIA ARBOREA (BLANCO) RADLK AGAINST FOOD ISOLATES

Rajeswari. R, Murugesh. S

Abstract :

The aim of this study was to evaluate the antibacterial activity of Harpullia arborea extracts against Gram positive and Gram–negative bacterial species. The antimicrobial activity was determined in the extracts using agar disc diffusion method. Among the both solvents extracts, methanol extracts showed good inhibitory activity against gram positive and negative isolates, zone of ranged from 10 mm to 18mm. The phytochemical analyses of the plants were carried out. The microbial activity of the Harpullia arborea was due to the presence of various secondary metabolites. This plant extracts which proved to be potentially effective can be used as natural alternative preventives to control food isolates.
